[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a flat Wi F i three-dimensional antenna, the flat Wi F i three-dimensional antenna comprises a shell 1, a partition groove 2 opened inside the shell 1, and a PCB mainboard 3 installed on the surface of the shell 1, the surface of the PCB mainboard 3 is provided with a radiation area 4 and a groove 5, the radiation area 4 is located on one side of the groove 5, the surface of the PCB mainboard 3 is provided with mounting holes 7, and the mounting holes 7 are arranged equidistantly;

[0025] Bolts 15 are installed on the surface of the shell 1, and the bolts 15 are arranged equidistantly. The bolts 15 are located inside the mounting hole 7. The shell 1 and the PCB mainboard 3 are connected to the mounting hole 7 through the bolts 15. The bolts 15 and the mounting hole 7 are connected through nuts, which can make the PCB mainboard 3 fit tightly with the shell 1 to increase the contact between the two, ensure good contact with the flat shell 1, and minimize interference with other circuit boards, thereby improving the performance of the antenna and improving the stability of communication of the PCB mainboard 3.

[0026] The radiation zone 4 is C-shaped and slot-shaped. The radiation zone 4 with the C-shaped slot-shaped setting has a lower cross-section, which is conducive to lightweight design in mobile devices such as tablet computers. At the same time, it can have a wider lateral opening, so it has a wider radiation angle and can achieve better coverage.

[0027] The inverted L-shaped arrangement of the groove 5 can make it have a wide operating frequency band and adapt to a variety of wireless communication standards and frequency bands. At the same time, it has good broadband performance and strong radiation directionality, and can concentrate the signal in a certain direction for transmission, thereby improving the directionality and security of communication.

[0028] A receiving plate 9 and a reflecting plate 10 are respectively installed on both sides of the PCB main board 3. The surfaces of the receiving plate 9 and the reflecting plate 10 are provided with positioning holes 8 arranged at equal intervals. A groove 14 is provided on the outer side of the reflecting plate 10. The setting of the groove 14 can facilitate a tighter connection between the PCB main board 3 and the shell 1, so that the groove 14 is just staggered with the structure of the shell and the surface of 1. The surface of the shell 1 is installed with a positioning bolt located inside the positioning hole 8, which can facilitate the positioning of the PCB main board 3 for its connection with the shell 1. The reflecting plate 10 is used to control the radiation direction of the antenna and enhance the receiving and transmitting performance of the antenna; the receiving plate 9 is used to receive signals sent from an external transmitting source and guide them to the antenna radiator for transmission or reflection to ensure the radiation direction and performance stability of the antenna.

[0029] Arc surfaces 6 are provided on both sides of the PCB main board 3 and at the connection points with the receiving plate 9 and the reflecting plate 10, which can facilitate the connection with the housing 1 and make it more tightly connected with the housing 1 to avoid a gap between the two.

[0030] An edge suspension plate 11 is fixedly connected to the top of the PCB main board 3, and a vertical angle of ninety degrees is formed between the edge suspension plate 11 and the PCB main board 3. The edge suspension plate 11 is rectangular and can be used to fix antennas and connecting cables and other components. The edge suspension plate 11 is usually provided with a terminal block or a connector to facilitate the connection of the antenna with cables, radio frequency modules, etc., which is not shown in the figure. A ground plate 12 is fixedly connected to the bottom of the PCB main board 3, and a C-shaped radiation area 4 is formed between the ground plate 12 and the PCB main board 3. The ground plate 12 is used to provide grounding and shielding functions for the antenna. During the communication process, the antenna will receive a large amount of background noise and interference signals. The ground plate 12 can help ground these noise and interference signals, thereby improving the signal-to-noise ratio and reception quality of the antenna. At the same time, the ground plate also plays a shielding role to prevent surrounding electronic equipment from interfering with the radiation of the antenna.

[0031] A spring clip 13 is fixedly connected to the bottom of the PCB main board 3, and the spring clip 13 is located on one side of the ground plate 12. There are two groups of spring clips 13, and the two groups of spring clips 13 are respectively located on the outside of the bottom of the groove 5. The spring clip 13 is located inside the partition groove 2. By arranging the spring clip 13 at the bottom of the groove 5, the bandwidth of the antenna can be increased, so that the antenna can work in a wider frequency range, and the gain of the antenna can be increased, and the signal receiving and sending capabilities of the antenna can be improved. By locating the spring clip 13 inside the partition groove 2, the PCB main board 3 can be preliminarily positioned on the surface of the shell 1 to facilitate the connection of the PCB main board 3 and improve its connection stability. In addition, installing the spring clip 13 at the bottom of the PCB main board 3 can increase the radiation symmetry of the antenna, so that the performance of the antenna can be further optimized.

[0032] During use, the PCB mainboard 3 can be installed inside the partition groove 2 on the surface of the shell 1 through the spring piece 13, and the positioning hole 8 and the mounting hole 7 are set on the surface of the positioning bolt and the bolt 15, and the nut can be tightened. In this way, the adhesive can be prevented from solidifying to form an uneven film, thereby affecting the performance and communication stability of the antenna. At the same time, through the setting of the arc surface 6, the connection between the PCB mainboard 3 and the shell 1 can be made tighter, avoiding the phenomenon of unstable connection between the two due to the structure of the shell 1, further increasing the contact between the two, ensuring good contact with the shell 1, and minimizing interference with other circuit boards, thereby improving the performance of the antenna and improving the communication stability of the PCB mainboard 3.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
